Well took the car in work today to get a brake fluid change when the technician noticed my crank pulley was a bit wobbly, well after investigating turns out something was vibrating causing the woodruff key to widen the hole in the crank and also mess up the cambelt and crankshaft pulley, this is the pulley compared to a new one..

oh dear, whoever did the last belt change can't have torqued and loctited it in Sad

from the mark on the back of the pulley it looks like a later hollow type pulley, which coincided with a change to the oil pump sprocket, meaning that if the bolt ever comes loose the pump still turns with the crank.

early ones just spin loose when the bolt is undone Sad

how bad is the damage to your crank?

I dont think its too bad, going to have a proper look tomorrow, you can wiggle the woodruff key slightly but the said it should be repairable, gonna check with a new one tomorrow

I've not had the belt done since the engine change as there was a reciept to say it was done about 10k before, maybe should have got it done really.
The old engine went (if you meant mine) because there was a big hole in the rad which caused it to overheat and seize, after doing all that we didnt know it weakend the bottom end!
Hopefully its repairable, Not a good thing to find out when you only want a brake fluid change though! LOL

Don't remember doing it up mega tight, which was probably the cause. The oil pump sprocket was visably spinning freely on the crank and oil pressure took a little while to build up.

Not a problem at all with my new engine, I remembered to do the bottom pulley up MEGA tight

The only reason that's happened is becuase it wasn't torqued up properly.

The woodruff key is elongated where the pulley has been rocking back and forth on the crank as the engine comes on/off load Yes

You have the resistence and momentum of all aux items being driven and slowed by that crank pulley, it'a got a fair bit of force on it which is why they slip in the first place Smile
